Under the council–manager form of government, an elected governing body is responsible for legislative functions such as establishing policy, passing local ordinances, voting appropriations, and developing an overall vision. The legislative body appoints a professional manager to oversee the administrative operations, implement its policies, and advise it. The manager position is similar to that of corporate chief executive officer (CEO), providing professional management to the board of directors. Council-manager government may also include the position of “mayor,” which is a largely ceremonial title, and may be selected by the council from among its members or elected as an at-large council member with no executive functions.
